Making a script to update and compile from CVS

Making a script to update and compile from CVS

[Lennart Borgman]

I saw someone made a try on EmacsWiki to automate the process of copying and
building Emacs from CVS. So I started to wonder how to do the building
process after a checkout update from CVS. There is no definitive answer in
INSTALL.CVS (unless you want to do "make bootstrap"). Doing "make autoloads
..." and "make recompile" are rather fast so there is no need to hesitate to
always do them (not even on an old pc like mine). Sometimes I have seen that
doing multiple "make recompile ..." are necessary.

Now I wonder in what order to do this. Should something like this be ok:

  (in lisp)
  make autoloads ...
  make recompile ...
  make recompile ...
  make recompile ...

  (in main)
  make
  make info
  make install

(This is of course not failproof, but maybe useful.) Could please someone
who knows this better please comment on the order of things etc here?

Hmmm, well I'm sure most developers have their own variation on this;
here's my works-most-of-the-time script (the "$E" parameter choose
which emacs tree to use, as I keep several different versions around):

#!/bin/sh
E="${1:-miles}"
BUILD="/usr/local/build/emacs/${E}"
SRC="/usr/local/src/emacs/${E}"
make -C$BUILD/lisp recompile					\
&& make -C$BUILD						\
&& make -C$BUILD/man						\
&& make -C$BUILD/lispref					\
&& make -C$BUILD/lispintro					\
&& sudo $SRC/admin/quick-install-emacs -vp $BUILD

Here is what I do, typically:

     % tla star-merge OR cvs update
     % (cd lisp; make updates recompile)
     % if some files failed to compile, (cd lisp; make recompile)
     % make

I don't actually do `make install' because I always work directly "in situ",
which is important when I do C-h f so I can click to get to the source and
start editing directly in the Arch/CVS tree.

Sometimes the above fails because the changes require a more
complex bootstrap.  In that case, I generally resort to my intuition and
knowledge to come up with an ad-hoc way to bootstrap, and if all else really
fails, I end up resorting to `make bootstrap' but since that takes a long
while I really make every effort to avoid it.

Sometimes the above succeeds but with incorrectly compiled .elc files
(typically because of macros which were not defined when the file was
compiled).  I catch those problems "lazily" (i.e. only when and if
I actually use the code).

Perhaps just for completeness' sake: I always bootstrap:

    make maintainer-clean
    ./configure ...
    make bootstrap tags
    make install

On Debian GNU/Linux, I use Jerome's wonderful package setup to
construct Debian packages.  I wish there was something similar for
FreeBSD ports.

Here is what I do:

;; updates:

    (progn
     (cd "/usr/local/src/emacs/")
     (cvs-update "/usr/local/src/emacs/" t))

;; Next, I run the fast `make recompile' command.  
;; The `make recompile' command recompiles all Lisp files which are
;; new; it does not create .elc files.  It only recompiles a file if
;; an .elc is already present.

     (progn
       (cd "/usr/local/src/emacs/")
       (compile
        "time make -C lisp autoloads && cd lisp && \
         time make recompile \
             EMACS=/usr/local/src/emacs/src/emacs && \
         cd /usr/local/src/emacs/ && \
         time make info html"))

;; (Once in a while I rebuild the DVI documentation by running 
;; `make info html dvi'.)

;; Occasionally, I run the `bootfast' command which recompiles all the
;; Emacs Lisp files.  I have been warned that sometimes an old .elc
;; file will cause trouble, but that has not happened yet.  Also, this
;; command deletes many other files.  This command takes a long time.

     (progn
       (cd "/usr/local/src/emacs/")
       (compile "date && time make bootfast"))

;; Finally, once in a great while, I configure and run `make bootstrap'
;; This takes a long time.

     (progn
       (cd "/usr/local/src/emacs/")
       (compile
        "./configure --with-type1 \
         --with-x-toolkit=gtk --with-pop \
         --prefix=/usr/local --with-sound=yes \
         && time make bootstrap"))

;; I have not had to update autoloads for months or maybe years, but
;; when I did, I used this command:

     (progn
       (cd "/usr/local/src/emacs/lisp/")
       (compile "make autoloads EMACS=../src/emacs"))

;; For installation, I run the following in a root owned instance of Emacs:

  (progn (cd "/usr/local/src/emacs/") (compile "time make install"))


;; To make tags, which I do occasionally:

  (progn (cd "/usr/local/src/emacs/") (compile "time make TAGS"))

Hi,

I checked out emacs in ~/nfs/Emacs/emacs--multi-tty And in
~/nfs/Emacs/openbsd and ~/nfs/Emacs/linux I run this ``script,''
which creates simple tarball packages, which you can install with:

tar xzf path/to/emacs\#21.3.50-$timestamp.pkg.tar.gz -C /

and uninstall with

cd /
tar tzf path/to/emacs\#21.3.50-$timestamp.pkg.tar.gz|xargs rm

Or get this simple package manager:
  http://www.fukt.bth.se/~per/pkgutils/

Or change the ``install_target'' to whatever you like:



MAKE=gmake
SRCDIR=../emacs--multi-tty
opties='--without-sound'
CFLAGS='-Os -g -pipe' # -DGC_MCHECK=1
PKG=$PWD/../fake

beep()
{
    echo -en '\a'
}

install_target()
{
    if [ -e $PKG ]; then
        echo sudo rm -rf $PKG
        sudo rm -rf $PKG
    fi
    $MAKE install DESTDIR=$PKG #prefix=$PKG/usr/local

#     find \
#         $PKG/usr/local/share/emacs/21.3.50/{leim,lisp} \
#         $PKG/usr/local/share/emacs/site-lisp \
#         -name "*.el"|while read line; do
#         if [ -r ${line}c ]; then
#             rm $line
#         fi
#     done

    find \
        $PKG/usr/local -type d  -name '.arch-ids'|xargs rm -rf
    rm -rf $PKG/usr/local/var/ $PKG/usr/local/bin/emacs-*
    beep
    echo 'Are you there?'
    read nop
    echo sudo chown -R root:wheel $PKG
    sudo chown -R root:wheel $PKG
    cd $PKG
    timestamp="$(date '+%Y%m%d')"
    gtar czf "../emacs#21.3.50-$timestamp.pkg.tar.gz" usr
    echo sudo rm -rf $PKG
    sudo rm -rf $PKG
    cd ~/nfs/Emacs
    echo "sudo pkgadd -u emacs\#21.3.50-$timestamp.pkg.tar.gz"
}

con_figure()
{
    CFLAGS=$CFLAGS CC=$CC $SRCDIR/configure $opties '--prefix=$(DESTDIR)/usr/local'
}

case $1 in
    bootstrap)
        [ -r Makefile ] && make maintainer-clean
        con_figure
        $MAKE bootstrap
        install_target

What about:

(progn
  (require 'tramp-util)
  (cd "/su::/usr/local/src/emacs/")
  (tramp-compile "time make install"))

Best regards, Michael.

[Richard Stallman]

I think it is a good idea to add a make target designed to encapsulate
everything recommended for people to do when building from CVS.
Or perhaps to add some of these things into the `bootstrap' target,
so that it will work in more circumstances.
